MASSAGING DEVICE.

Application led January 17, 1925.

` This invention relates to an improvement in massaging apparatus of thetype employing a plurality of rollers which are rotated bodily and whichrotate about their own axes, and the object of the invention is toprovide a device of this character which may be adjusted to cause therollers to engage with the flesh to the desired extent and which iseffective to increase circulation and to exert a general good effect onthe parts of the body on which it is used.

A further object is the provision of an apparatus'of this characterwherein the rollers are so constructed as to provide a lingering orkneading action when rolling the iesln A still further object is theprovision of an apparatus of this character which is of simple anddurable construction, reliable and efficient in operation and simple andinexpensi ve -to manufacture.

Other objects and advantages reside in certain novel features of theconstruction, arrangement and combination of parts which will behereinafter more fully described and particularly pointed out in theappended claims, reference being had to the accompanying drawingsforming a part of this specification, and in which:

Figure l is a perspective View of a preferred embodiment of theinvention,

Figure 2 is a view partly in side elevation and partly in longitudinalcentral vertical section further illustrating the device shown in Figure1 but showing smooth roliers,

Figure 3 is a view in end elevation leeking to the left of Fig. 2 butshowing a differ ent type of roller.

Figure 4; is a view in section ll`4 of Figure 2 I Figure 5 is a detailView in elevation of the referred form of roller., and

Figure 6 is a detail view.

Referring to the drawings, the numeral 1 designates a motor which issupported on and secured to a bracket 2. The bracket 2 is integrallyformed with or suitably connected to a cover 3 which has a flange 4secured by screws 5 to one end of a gear casing 6.

The motor 1 has an armature shaft 7 which extends into the gear casingGthrough an opening 8 in the cover 3 and the portion of the armatureshaft within the gear casing has a pinion 9 fixed thereto. The pinion 9meshes with an internal ring gear 10 carried on the outer ends of spiderarms 11.

en the line .The spider arms 11 are integrally formed Serial No. 3,162.

with a hub l2 which is fitted on and secured to one end of a rotatableshaft 13. Bearings 14 and 15 are provided within the gear easing 6 andin these bearings 14 and 15 the shaft 13 is rotatably mounted.

The shaft 13 projects forwardly from the gear casing 6 and on itsforward enda block 17 is threaded. The block 17 may take the forni of anut and is held in position in any suitable manner. A carrier block 16is attached to the block 17 by screws 16". A plurality of radiallyextending studs 18 are carried by the block 16, the studs 18 havingthreaded portions 19 engaged with internally threaded openings providedin the blocks 16 and held in such openings by set screws 20. The majorportions of the studs 18 are smooth and on such smooth ortions rollers21 are rotatably mounted. earings 22 are provided for each roller, andone end of each bearing engages a head 23 provided on each stud 18. Therollers shown in Fi 2 and 3 have smooth peripheries but t e preferredform of roller is shownin Figures l and 5 and has its periphery serratedor formed with alternate ridges 25 and grooves 26. This serrated orcorrugated form of roller exerts a fingering or kneading action on theflesh when the rollers are engaged therewith.

As described and as shown in the drawings the rollers are mounted onthat por tion of the shaft 13 which is located outside of the gearcasing 6. The gear casing 6 is preferably of c lindrical form and aguard sleeve 30 is sli ably fitted on this gear casing 6. The forwardend of the guide sleeve is flared outwardly, as indicated at 31, and isrounded and smooth. Longitudinal slots 32 are provided in the sleeve 31and through these slots threaded Shanks 33 of set screws 34 extend. TheShanks 33 are threadedly engaged with threaded openings 35 provided inthe ge'ar casing 6. Shoulders 36 are forn'ied on the set screws 34 andare engageable with the periphery of the sleeve 30 adjacent the slots32. The heads of the set screws are flattened out and provided withwings, as indicated at 37, in order to facilitate'manipulation of theset screws. With this arrangement the guard sleeve 3() may be'adjustedto overla the rollers to the extent desired. This eature Ahas theadvantage of controlling the degree at which the 1lllolllrs operate uponor contact with the In operation, the rollers are applied to the part ofthe body to be treated and, as stated, the degree with which the rollerscontact is regulated by the guard sleeve 30. The

motor 1 is then started and turns the shaft 13 through its shaft -7 andthe gears 9 andk 10. The rotation of the shaft 13 causes the rollers torotate bodily and the'traction of the rollers on the flesh causes themto rotate on their individual axes. Int-his way motor mounted on thebracket and having its armature shaft projecting into said casing, a'pinion Cn the shaft Within the casing, a shaft mounted in the gearcasing, a rin gear carried by the inner end of the sha t and 'i 25 withwhich the said pinion meshes, a mem- `ber secured to the outer end ofsaid shaft and having a plurality of radial studs, rollers looselymounted on the studs, a uide sleeve having a flared end and adjusta lysecured to the gear casin and a handle secured to the peripheries o themotor and gear casing.

2. In a massaging apparatus, an openended gear casing, a cover for theinner end of the casing, a bracketprojecting from the cover, an electricmotor mounted on the bracket and having its armature shaft projectinginto the gear casing through the cover thereof and having a. pinion onits end, a shaft mounted 1n the gear casing, a ring gear with which thepinion meshes,

means for mounting the ring gear on the inner end of the shaft, apluralityof rollers, and means for mounting the rollers on the outer endof said shaft, whereby they may rotate' bodily and about their ownaxis.l

3. In a massa-ging ap aratus, a gear casing havingy its outer en openand its inner end closed, an electric motor mounted at the inner endofthe casing and having its arma- -ture shaft extending into the casin apinion on said end of the shaft, 'a s aft mounted` in the casing, aspider secured to the inner end ofthe shaft and carryin a ring gear withwhich the pinion mes es,

and a plurality of rollers mounted on the outer end of the shaft torotate with the shaft and about vtheir axis.
